            Bug ID: 90446
           Summary: ICE: Segmentation fault in build_function_type at
                    gcc/tree.c:8539
           Product: gcc
           Version: 9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: d
          Assignee: ibuclaw at gdcproject dot org
          Reporter: ibuclaw at gdcproject dot org
  Target Milestone: ---

Only seen on msp430-elf, happens because LANG_HOOKS_TYPE_FOR_MODE is given a
PSImode for the BT_UNWINDWORD type, returning NULL, and later segfaults when
generating BT_FN_UNWINDWORD_PTR.
